And, attic insulation is one of the very best home improvement projects for a great return on investment. There are also some pretty great tax credits when it comes to attic insulation.

How do you know when you need attic insulation?

If your home experiences any of the following symptoms, you may want to consider adding adequate levels of insulation to your home’s attic along with its interior walls, floors, and crawl spaces. Give us a call straight away if your home have any of these issues:

  • High heating or cooling costs.
  • Uneven temperatures between rooms.
  • Draftiness.

What kind of insulation should you choose?

If your home is not properly insulated, you are likely paying much more than you should be for home energy. There are a few different options in attic insulation, all with different R-values. Understanding an insulation material’s R-value – a measure of how well it resists the flow of heat is important; the higher the number, the better the insulating power.

Spray foam – Closed cell spray polyurethane foam (SPF) is a premium insulation perfectly suited for the attic. With a high R-value, it acts as a barrier to keep the indoors from the outside climate, creating thermal, air and moisture isolation. It can expand and reach hard-to-till voids that other insulation types are not able to do.

Fiberglass and Cellulose Attic Insulation – These types of blown-in insulation have almost the same R-value, and they are both environmentally friendly. Cellulose is made out of recycled newspaper and fiberglass is made out of sand, both of which are renewable resources.

These types of insulation are great for filling in gaps and ensuring your entire attic is evenly insulated. The installation process is generally pretty quick, depending on the size of your attic.

Give us a call and we can advise you on which type of attic insulation will best suit your needs and keep your home warm in the winter and cool in the summer.

  • What is fiberglass insulation? Fiberglass insulation consists of extremely fine glass fibers, sand and is the type of insulation found in most homes. It is commonly used in two different types of insulation – blanket which is batts and rolls, and loose fill. Fiberglass can be placed in unfinished walls, floors and ceilings. It is fitted between studs, joists, and beams.
  • Fiberglass as an insulator slows the spread of heat, cold, and sound in structures. The material does this by trapping pockets of air, keeping rooms warm in the winter and cooler in the summer.
  • An often overlooked feature of fiberglass insulation is that it is eco-friendly, which is particularly important if you are worried about your carbon footprint. It is made out of sand and recycled glass, both of which are renewable resources.
  • Fiberglass insulation is also non-combustible, non-absorbent and non-corrosive. It will not hold water, so you never have to worry about moisture issues as a result of this type of insulation.
  • Fiberglass insulation is cost-effective but also gives you year-round comfort. You and your family will be warm and toasty in the winter and cool and comfortable in the summer thanks to fiberglass.
  • The type of fiberglass insulation we install is mold and mildew resistant. So you will not have to worry that your new fiberglass insulation is retaining moisture.
  • Fiberglass insulation is also budget-friendly. You still get many of the same perks as other types of insulation, but fiberglass is one of the least expensive options on the market today.

Get a Cooler Attic this Summer with Attic Ventilation

With hot weather here to stay for the summer, it is a good time to start thinking about ways to help keep the house cool. One of the most important parts of keeping your home cool is proper ventilation. As professionals in attic ventilation for Maple Grove, we would like to tell you more about attic ventilation and why now is a superb time to consider having it properly addressed by experts.

Attic Insulation & Ventilation Maple Grove

In the summer, natural air flow in a well-vented attic helps to release the hot air out of the attic. This helps assist your air conditioning, keeping cooling costs low and your home comfortable. Have some more questions about attic ventilation? Here are a few of the most common ones we hear:

How do you know if your attic is properly ventilated?

Most attics require air chutes to circulate proper air flow. Air chutes are placed between the rafters in the attic, and go down into the soffit to bring up proper air flow. The size of the attic determines how many air chutes are recommended for optimal venting.

Why does attic ventilation help in summer?

At first it may seem odd to add insulation for warmth and then purposely allow cold air to enter the attic through vents, but this combination is the key to a durable and energy-efficient home. In the summer, natural air flow in a well-vented attic moves super-heated air out of the attic, protecting roof shingles and removing moisture. The insulation will resist heat transfer into the house.

What types of problems can a poorly insulated attic cause?

Inadequate venting in your attic causes all sorts of problems, including wood rot to mildew, peeling paint, rusty nails or screws, roofing problems and even energy loss.

The good news is that these issues can be easily prevented by simply venting your attic correctly.

Do you still have some more questions about attic ventilation? Give us a call us at Lewis Insulation and we can get you scheduled for a visit. We will come out and take a look to determine proper ventilation, whether you have it or not. Whatever the reason you might think you need better attic ventilation, you should talk to a professional to determine what your home needs.

Considering insulation work for your home? Did you know that closed cell spray foam insulation can keep a house not only warm in the winter, but nice and cool in the summer?

As you are well aware, it is important for homeowners to keep their homes cool without having to run their AC unit at all times, running up their monthly energy bills. That’s where high quality, properly installed closed cell spray foam insulation comes in! How it all works:

In order to keep a home cool in the summer months it is usually necessary to either use a window air conditioning unit or central air unit. These machines are the only thing that create cold air, as every other appliance radiates heat. This is where spray foam insulation plays its part. Heat transfer and air flow both contribute to the comfort and energy efficiency of a home. With closed cell spray foam insulation you create a barrier to keep cool air from escaping and hot air from getting in. Spray foam insulation completely fill the cavities, including any gaps and crevices in your roof and walls stopping any air leakage and movement.

While other types of insulation are great at this, closed cell spray foam insulation is simply the best as it provides both heat resistance and an air seal. It’s really able to get into the nooks and crannies of the home.

With closed cell spray foam insulation your air conditioner also won’t need to run constantly in an effort to maintain a constant temperature. This will save you money in the long run on your monthly energy bills as well as on maintenance for your AC unit.

In conclusion, closed cell spray foam insulation is a smart choice year round because it’s great at creating an air seal in your home and creating a barrier that will hold in those comfortable temperatures.

As you can see, there are many reasons closed cell spray foam insulation can benefit you and your family this summer!
